Let's solve this step by step:

Step 1: Let's assume the present ages of P and Q are 7x and 3x respectively.

Step 2: According to the problem, after four years their ages will be in the ratio 2 : 1. So, we can write it as (7x + 4) / (3x + 4) = 2 / 1.

Step 3: Solving this equation, we get 7x + 4 = 2 * (3x + 4), which simplifies to 7x + 4 = 6x + 8.

Step 4: Subtracting 6x from both sides, we get x = 4.

Step 5: Substituting x = 4 in 7x, we get the present age of P = 7 * 4 = 28 years.

So, the present age of P is 28 years.
